Introduction

Since DSpace version 1.8.X. and greater, the search indexes are delivered via the "Discovery" facility using the SOLR service.

The Discovery Module enables faceted searching & browsing for your repository.

DSpace Discovery offers very powerful browse and search configurations that were only possible with code customization in the past.

With DSpace versions =>4.X Discovery is now the default.

Requirements

Before attempting setup please make sure the following are correct:

  1. Tomcat is listening on TCP port 80.
  2. The SOLR webapp is correctly published.

For DSpace 4.X

For DSpace 3.X

For DSpace 1.8.X

Tips

To check configuration, run the following: 

/home/dspace/bin/dspace dsrun org.dspace.discovery.configuration.DiscoveryConfigurationService

Install the "lynx" application. 

sudo apt-get install lynx

Then type the following in the console: 

lynx http://localhost/solr

If not debug the solr webapp until you can.

Remember to restart the Tomcat server for each change you make to a webapp configuration.
